With this add-on you can set a list of (sub)domains which should be blocked. What is special about this add-on is the fact it doesn't require risky permissions.
Each time you update the blocklist, unused permissions are removed and permission for the new domains is requested to be able to block them.
Currently no path matches are supported. This is due to the fact the blocklist is not stored in browser storage (thus, no storage permission is needed). The blocklist is stored using the domains the add-on has access to.
